Other claims from this paper (6)
- Intervention effect Earthworms fed GM or non-GM maize showed no significant differences in survival, body weight and cocoon production after three generations in the laboratory.
- Intervention effect Superoxide dismutase and catalase activities did not differ significantly between GM and non-GM maize varieties.
- Observation Exogenous Cry1Ab and EPSPS proteins were undetectable in the gut tissues of earthworms raised with GM maize straw.
- Intervention effect GM maize cultivation had no adverse effect on species composition or density of soil earthworms in two years of field testing.
- Intervention effect Total number of earthworms did not significantly differ between GM and non-GM maize lines in the field.
- Recommendation The authors conclude that cultivating GM maize variety DBN9936 does not pose a risk to earthworms.
